CDM 7SE
Floor-standing loudspeaker system
The CDM 7SE has an additional paper/Kevlar® bass driver which delivers a fast bass
response.
The technology has been advanced even further in the CDM 7SE. The bass units now
feature dispersion modifiers in the centre of the voice coils. Replacing the normal dust
caps, these improve dispersion in the mid frequencies and give better integration between
the drive units, resulting in greater detail and dynamics.
The crossover boards incorporate tweeter filters, maximising the benefits of bi-wiring. The
stunning aesthetics hide a simple fact that the panoramic, studio quality sound delivered by
these speakers is rarely equalled.
Technical highlights
Tweeter on top: B&W's Tweeter on top technology ensures that the sound
remains focused and time-sensitive and that the stereo-image is presented with
unparalleled three dimensional accuracy.
Kevlar®: B&W developed and patented the method of using Kevlar® for
loudspeaker cones to reduce unwanted standing waves. DuPont originally
created Kevlar® for use in bulletproof vests.
